I was watching Netflix on my hp envy 15t-ae100 with an i7 processor when all of a sudden it made a loud static noise through the speakers (even though I had headphones plugged in) and shut down. It will now rarely turn on and if it does it only stays on for a minute or so. It seems to work slightly better when it is low on battery. I took it to geek squad and they said it was overheating and the fan wasn't working. I do believe it has a virus, but it also has some sort of other issue with the hardware (other than the fan). Any ideas? Please help
